flotation has become the most important and efficient method for lithium ores processing 20 . Previous studies showed the possibility of obtaining high-lithium grade concentrates by froth flotation from Portuguese ores as are the cases of amblygonite Argemela deposit and spodumene Barroso assaying values close to the
A method of beneficiating garnet-containing ore which comprises subjecting the ore to froth flotation in the presence of a collector containing as its effective constituent water soluble petroleum sulfonates and an effective amount of sulfuric acid the amount of the latter being sufficient to modify the flotation characteristics of the garnet particles whereby a concentrate is obtained relatively rich in garnet and a
Hybrid Flotation Technology combines a pneumatic spray principle with a column method. The technology is based on the merging of feed pulp slurry and gas
The ores smaller than ¾” were stocked in ore bin while the ores larger than ¾” were crushed by jaw crusher again. The flow sheet of crushing process is shown in Fig. 1.
Types of Flotation ReagentsFlotation ReagentsFlocculantsList of Flotation Reagents and Flotation ChemicalsFlotation Reagent PumpsGold Mining ChemicalsFlotation reagentsmay be roughly classified according to their function into the following groups: Frothers Promoters Depressants Activators Sulphidizers Regulators. The order of these groups is no indi ion of their relative importance; and it is common for some reagents to fall into more than one group.
